Echo 7310 Power vs 800P

[Flexwingman]

I have a tree felling business and also work full time. I run 7 different Echo saws and have had no issues with any of them. I've run 32" bars on the 800p. The 800 gets the job done, yet I'm sure there are more powerful saws that weigh less in that size range. Still, they are a decent tool and hold up really well. I'm now looking at the 7310 to run a 32" bar. I have yet to find a dealer that has real information or experience with these two saws. My saws are tools and not for fun. I need at least a 32" bar to cover most of the larger trees here in the Midwest. It really gets me when I see dealers selling a 7310 with a 20" bar.
My unanswered questions are:
Will the 7310 pull a 32" bar better than the 800p? I know they say it has more HP, but does it have more torque? I question the 7310 because Echo rates it for up to a 32" bar. The 800P is rated for up to a 36" bar. If the 7310 has 15% more power than the 800 as stated on Echo's site, then why is it only rated for the 32" bar max?? Not one dealer can tell me they've actually run both and can answer the question.
Anyone have experience with both in basic stock form running equal length bars, full comp or skip chain??

7310 has more hp but a narrower power band. It will pull shorter bars faster but may struggle more with a 32 on it

The echo 800 will pull a 32 far better then the 7310

I have a new 7310p with a 28" bar that I have not used but I will be removing the 28 and replacing with a 20 until the saw is broken in.

I really do not understand Echo, they had an opportunity to garner more market if they had made the 7310 with 77 or even 78cc powerhead = 7810p

It should be a 7810p to compete with Stihl MS461/462, Dolmar 7910 and Husqvarna 572xp/585

I’ve been curious about this too. I’ve spent some time behind a 800 but have never run a 7310. I know the 800 is a strong saw on the low end. It doesn’t get a lot of love but like the 680, it pulls long bars in its weight class fine. I run my 680 with a guy who has a 362. In smaller wood the ms362 spanks it but by the time you are burying a 24 inch bar, the 680 pulls way ahead and can pull a 32 inch all day. A little more displacement too. Just different power bands. New strato vs old torque. At least the 7310 isn’t strato.

It makes sense that the 800 would have more torque being a longer stroke and bigger cc engine. If that's true, Echo messed up.

Had Echo spoke with me, or you, we would have a CS-7910P and the 800 would be done over into a 880P or a 9210P.

I've even called Echo corporate and they had no one that could answer these questions. I'll just stick with my 800's until they build a bigger saw. Good forum, thanks!

Like you, I am hoping that Echo revamps the 800 into a larger CC new design saw like the 7310p.

I have only been starting my new 7310p to let idle for 5 minutes per startup for a slow process break-in.
Currently MS460 handles any big wood and my muff mod 590 does most cutting along with a 501P

And can we get that 27cc CS-271T cylinder on the CS-2511T = that would be 'lights out' in a top handle under 6lbs

I dropped and bucked up this tree with the 800 and a 32" bar. I had to notch and backcut it from both sides. The bar was way short. I've cut lot of trees almost as large and the 800 works.

Maybe it is just a distortion of the picture but it looks like you are on a steep downside.
A log that size can break a leg or worse.

A farmer cutting by himself in dead of winter, near 0 temp, got his leg pinned under a log that size and he had to cut his leg off and crawl back to the truck to save his life.

I have a 7310 broken and I’m more than happy with it. It’s basically a modern oe 372 as far as power and size. With a 24 inch bar I have no issues with power, a 32 inch bar would be pushing it.

It seems like you might be better suited by a Stihl 661 or 500i; the new husky 592 is also getting great reviews. If you want to step it up member RobinWood has Echo 1201’s in stock in the trading post. That’s a heck of power head and should really make you smile if you’ve been happy with your 8000’s.

No worry, I moved things around and went to the other side when cutting through.

Only thing I don’t like about the 800 is the carb box and filter design. If it were just a bigger version of the 680 with the automotive style filter, it would be my favorite saw. I love the build quality, the thumb pump oiler and the outboard clutch. I’m not picky about weight. I use heavy saws for big wood on the ground and felling.

Did you take a read of the reviews on the Echo-USA site? I know, they're reviews and you can't always trust them, but it seems folks are pleased with its performance using the 32" bar. There is even one guy who claims to be running a 36" bar. Here is the link to his review: CS-7310 36" Bar review

 

[rmh3481]

Joe is getting close to 8hp out of the 8000. You can easily pull a 36 inch bar with that.

Some videos of ported 7310 saws I seen they were pretty wicked looking in the cut.

Follow up on my question:
I bought a 7310 with the 32" bar despite some dealers that sell both Husky and Echo saying a saw in the 70cc range isn't strong enough to pull that long of a bar. Being in the business of tree felling and getting by with the 800P, I figured I'd answer the question myself. I know there are much stronger saws than the 800, but it will do the job and has paid for itself 10 times over in the last 4 years. I did buy a new carb for the 7310 just so I could figure out the limiters and make a tool that would fit the half screws H and L needles. Both were easy to do without removing the carb from the saw, and now I can easily tune while the saw is running. I also pulled the muffler and it's wide open and feel there's no need for any mods. I did remove the screen. I run all my 8 saws on Amsoil Saber at a 50-60 to 1 ratio.
What I learned after just two tanks of cutting large logs that were 32 plus inches:
Is this saw as strong as a 90cc Husky or Stihl? No. Does it pull the 32" bar better than the 800P? Absolutely! It not only revs much faster, but has more torque. I can stop it in the cut, keeping pressure on the bar, and it will take right off from an idle where the 800p would bog down. I see no reason for any porting. Echo has done their homework on this one. It's a hot saw for sure. I'll keep the 800s for stumping. The other plusses on the 7310 is its lighter weight, better air filter, and side chain adjust.
Last thought: For running a 24" bar or shorter, I'd stay with the 620P vs. the 7310 because the 7310 weighs more. If you use saws for work, there's no reason to wear yourself out with added weight unless you need it for a long bar and big trees. The 620P handles a 24" bar just fine.

 

[Brufab]

I put a 34" on my 590 didn't do to bad actually. Not a everyday set up but if you needed to make a few cuts every now and then should work fine. Seemed to oil ok as well.

Hotsaws101 on YouTube made a pretty interesting video on the 7310. Definitely worth a watch.

The saw isn't what most think it is. The stroke is longer in these Shindiawa and Echo newer offerings out since 2020. Have one here, well gone now, but it has a 30" 375 050 full comp on it with WCS three points. It just for bucking with mods but the jug is stock. Owner is very happy with it compared to stock but still running that 60+ quench. They don't like much timing advance either. It did like all the intake work and a dual port muffler. Time will tell he bucks all hardwoods with it. Oak Beech and Maple mostly.
